Nanocellulose can be divided into three main categories:
1. Cellulose nanocrystals (CNCs), also known as cellulose whiskers
CNCs are produced by disintegration of cellulose fibers into nanoscale particles (top to bottom process). CNCs are commonly produced using acid hydrolysis of cellulosic materials dispersed in water.
2. Cellulose nanofibrils (CNFs), also known as nanofibrillated cellulose (NFC), microfibrillated cellulose (MFC) or cellulose nanofibers
CNFs are produced by disintegration of cellulose fibers into nanoscale particles (top to bottom process). CNFs are produced by high-pressure grinding of cellulosic pulp suspension and strongly entangled networks of nanofibrils are formed
3. Bacterial cellulose (BC) and electrospun cellulose nanofibers (ECNFs)
BC and ECNF, the low molecular weight sugars or dissolved cellulose are generated by bacteria or electrospinning, respectively (bottom to top process)
